New alternator, flickering lights

[Fless]

The amp spec is usually stamped on the alternator housing. And the 145a usually has the dark gap between the case halves, while the 105a does not. 145a shown:

Glad it got taken care of by them. It's always good when they stand behind the product with no grief to customer.

Did you ever figure out if is 105 amp or 145 amp?

 

[Timc9516]

Yea it was the 145 amp the 105 amp uses a smaller belt

what you were experiencing is called diode ripple...an alternating current leak through the diodes...with a description of your concern the alternator should have been exchanged the first time you brought it in...

the diodes change alternating current to direct current to operate your vehicle...a failing diode will leak a "ripple" on the dc current and can screw up a lot of things...many transmission concerns are alternator related due to the electronic controls...
